IP link to connect host to macvlan containers breaks after a couple of seconds - docker

Question

I have a macvlan network where i put all my containers in. It was created like this:
docker network create -d macvlan -o parent=eno2 \
--subnet 10.0.2.0/24 \
--gateway 10.0.2.1 \
--ip-range 10.0.2.0/24 \
mynet
This is allows for container <-> container communication and from external computers <-> container communication. The problem is that host <-> container communication is not possible.
Searching about how to fix this, i found this blog.
That solution appears to work, running this commands:
ip link add zrz-ch link eno2 type macvlan mode bridge
ip addr add 10.0.2.15/24 dev zrz-ch
ifconfig zrz-ch up
I can successfully ping any container, and any container can ping the host.
The problem is that after 5-10 seconds the link breaks and the communication does not work anymore.
Ping from host -> container:
root#pluto:/home/zrz# ping 10.0.2.10

As you see after 5 seconds~ it stops working, the same happens when pinging from container -> host (after running the above commands on the host)
I can ping again if i do
ip link delete zrz-ch
And then run the commands above again. But as i said, it breaks after a couple of seconds.
How can i fix this?
Any ideas of how can i fix this?
